Riverside broke a heat record for the second consecutive day as a heat wave continued to bake the region, even after thunderstorms loomed over some areas Saturday.

The mercury in Riverside topped out at 113, beating out a high of 109 for the day set last year, according to the National Weather Service.

Elsewhere in the county, Corona reached 105 degrees, Beaumont 100 degrees, Palm Springs 115 degrees and Thermal 116 degrees, the agency said.

An excessive heat warning for the western portion of the county will continue until 9 p.m. Saturday.

Monsoonal moisture combined with the heat to bring a bout of afternoon thunderstorms that dropped 0.16 inches of rainfall on Moreno Valley and the San Gorgonio Pass, according to preliminary NWS figures.

Forecasters expect a small dip in temperatures Sunday with a slight chance for more thunderstorms, especially in the mountains.

The NWS issued a reminder that “young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.”

County health officials advised locals to take advantage of the 56 cooling centers that opened to the public this month and are available at no cost. A list of cooling centers can be found at www.capriverside.org.

Sunday’s forecast for Riverside is 105 degrees, with 100 predicted for Monday before temperatures go back under triple digits beginning Tuesday, where they are expected to stay throughout next week.
